A firearm is an emergency life-saving rescue tool

Critical tools need to be up and running when you need it. Semi-automatic handguns are not immune to misfeeds and malfunctions. Most issues can be cleared by ejecting the old magazine, racking the slide to release any stuck ammunition, and inserting a new magazine. Also, spare magazines allow compact carry guns the capacity to handle multiple deadly threats. Lastly, the magazine release can be accidentally pressed during a struggle for the gun. Having a spare magazine brings you back into action. Prepare for the worst, hope for the best.
